磁化镀液化学镀层的微观结构

Microstructure of Deposit of Magnetized Electroless Plating Bath

镀液磁化得到的Ｎｉ－Ｐ化学镀层组织致密，孔隙也较少，经光学金相及透射电镜分析为Ｎｉ２Ｐ、Ｎｉ７Ｐ３、Ｎｉ１２Ｐ５等组成的晶体组织。

After electroless Ni-P solution being magnetized, an electroless deposit, which is compact in structure, low in porisity, is obtained It is demonstrated with TEM that the deposit is crystalline (Ni_2P、Ni_7P_3、Ni_12P_5) and in normal case the deposit is noncrystalline
